Providing services using a device capabilities service

ABSTRACT

Systems and method provide logic for providing a service. In one implementation, a computer-implemented method provides a service to a device based on a capability of the device. The method includes identifying a device type of a device based on information associated with the device. The method determines whether the device supports the service, based on at least the identified device type, and provides the service to the device, when the device supports the service.

BACKGROUND

Online entities offer a wide variety of electronic content and services to a variety of different devices, including personal computers (PCs), electronic book viewers, portable digital assistants (PDAs), mobile telephones, pocket PCs, smart phones, televisions, set-top boxes, digital video recorders (DVRs), and gaming consoles. These devices often access various web pages and web services, such as those associated with online stores or other providers of audio/visual content, software programs, digital books, or other electronic content. Further, these devices generally incorporate a wide variety of hardware and include a wide variety of operating systems and software applications.

For example, processes that provide access to electronic content and services generally require a user of a device to access a login page and enter authentication credentials, including a user name and/or a password, prior to completing a request for electronic content or services. However, these processes are generally unable to discern whether a combination of hardware and software associated with a particular device supports the requested electronic content. These processes, in general, merely provide the requested electronic content to the device, while leaving to the user the task of determining whether the device supports the electronic content.

Further, even a user who is familiar with the capabilities and features of a device may be unable to easily identify electronic content supported by the device. For example, web pages and services associated with providers may organize electronic content and services according to title or functionality, but not according to a file format associated with the electronic content, specific hardware and/or software applications required by the electronic content or services, or other parameters indicative of whether the device supports the electronic content. Although capable of accessing web pages and services to obtain electronic content, many devices may be unable to easily parse the displayed data to identify supported electronic content based on specific software-related or hardware-related features. Therefore, systems and methods are needed to overcome the limitations of traditional processes that provide electronic content and services to devices.

However, in additional embodiments, capabilities data store 606 may be included within one or more external memory devices in communication with device capabilities server 126 via network 130 using, for example, network interface 608.

FIG. 8 is a flow diagram of an exemplary routine 800 for providing a service, consistent with disclosed embodiments. As described above, system 100 provides functionality enabling a fulfillment server, e.g., fulfillment server 122, to provide a service to a device, e.g., device 102, based on a capability of device 102. Routine 800 provides further details describing how fulfillment server 122 provides a service to device 102 based on a capability of device 102.

In block 802, fulfillment server 122 identifies a service associated with a capability. In such embodiments, the identified services may include, but are not limited to, providing electronic content to device 102, authenticating device 102, communicating with device 102, granting permission to device 102 to perform an action, transmitting error and/or informational messages to device 102, and any additional or alternate service apparent to one of skill in the art.

Further, as discussed above, the capability associated with the service may indicate an ability of device 102 to view, edit, save, or otherwise process a particular variety of electronic content, e.g., content that is available from fulfillment server 122. For example, the supported capability may indicate whether device 102 is compatible with a particular file format (e.g., a PDF file), whether device 102 can download specific electronic content (e.g., electronic books, newspapers, and/or magazines), and whether device 102 supports content presented at a specific visual resolution.

However, the capability is not limited to an indication of allowable content. For example, the capability may also include, but is not limited to, features of software supported by device 102, communications and/or security protocols associated with device 102, location-specific capabilities and limitations (e.g., an ability to download and/or transmits files in certain geographical regions or countries), connection-specific capabilities and limitations (e.g., an ability to downloaded electronic content when device 102 is roaming or has a poor signal), user-specific capabilities and limitations (e.g., user preferences), device-specific capabilities and limitations, or any additional or alternate capability apparent to one of skill in the art.

In step 804, fulfillment server 122 identifies a device type associated a device, e.g., device 102, based on at least information associated with the device. For example, the information associated with the device may include user information. In an embodiment, the user information may uniquely identify a user of the device, and may include, but is not limited to, an account number of the user, a personal identification number of the user, a login credential of the user, or any additional or alternate information that uniquely identifies the user of the device. In an embodiment, described above, fulfillment server 122 may transmit at least a portion of the information associated with the user to the device management server to identify the device type.

Device management server 124, upon receipt of the user information, may compare the received user information with corresponding information of records within a data store, e.g., device data store 406 of FIG. 4, to retrieve a record having user information that matches the received user information. In addition to including user information, the retrieved record may also include device information that is linked to the user information of the record. The device management server may subsequently process the retrieved record to extract the device information associated with the received record, and transmit the device information to fulfillment server 122.

As discussed above in reference to FIG. 5, the data record retrieved by device management server 124 may include device information that identifies device 102 (e.g., device information 512 of record 500). In an embodiment, device information 512 includes a device type (e.g., device type 514) associated with the user information retrieved from fulfillment server 122, and device management server 124 may extract device type 514 from the retrieved record and transmit device type 514 to the fulfillment server.

However, the retrieved record may include additional information identifying device 102, including, but not limited to a model number of device 102 (e.g., model number 516) and a serial number of device 102 (e.g., device serial no. 518). In such an embodiment, the device management server may also extract the additional identifying information from the retrieved record, and forward that extracted information to fulfillment server 122 with the extracted device type.

Once the device type is identified in block 804, fulfillment server 122 determines in block 806 whether device 102 supports the service. In an embodiment, fulfillment server 122 first processes the service to identify a capability associated with the service. The identified capability and at least the device type may then be transmitted to a device capabilities server in block 806, e.g., device capabilities server 126 of FIG. 1. Further, additional information associated with device 102, e.g., a version of an operating system executing on device 102, a model number of device 102, and a serial number of device 102, may also be transmitted to device capabilities server 126 in block 806. As discussed above, the device type, and any additional information associated with the device, may be obtained through interaction with device management server 126, and additionally or alternatively, may be received directly from device 102.

The fulfillment server may receive a response from device capabilities server 126 that, in an embodiment, indicates whether the identified device type is associated with the capability of the service. Fulfillment server 122 may then determine in block 806 whether device 102 supports the capability based on the response received from device capabilities server 126. Additional details regarding the interaction between fulfillment server 122 and device capabilities server 126 are discussed below in reference to FIG. 9.

If it is determined in block 806 that device 102 supports the capability, then fulfillment server 122 provides the service to device 102 in block 808. However, if it is determined in block 806 that device 102 does not support the service, then fulfillment server 122 may transmit an error message to device 102 in block 810 over network 130. For example, the error message may indicate that the service is not supported by device 102 and, additionally or alternatively, provide information relating to additional hardware and/or software components the facilitate access to the service. Such information may include, but is not limited to, instructions for configuring device 102 to support the service, or a link to a website or other service that provides an application program supporting the service.

In an embodiment, fulfillment server 122 may provide electronic content to device 102. For example, fulfillment server 122 may receive a request to access electronic content from device 102, and routine 800 may provide device 102 access to the requested electronic content based on a capability of device 102. The requested electronic content may include, but is not limited to, one or more of an electronic book, a digital audio file, a digital video file, a digital media file, a digital image, an application executable by device 102, and any additional or alternate electronic content apparent to one of skill in the art and appropriate to device 102.

In such embodiments, fulfillment server 122 may identify a device type associated with device 102 in step 804, and fulfillment server 122 may determine in block 806 whether device 102 supports the requested content. If it is determined in block 806 that device 102 supports the requested content, then fulfillment server 122 may provide the requested content to device 102 in block 808. However, if it is determined in block 806 that device 102 does not support the requested content, then fulfillment server 122 may discard the request and may transmit an error message to device 102 in block 810.

For example, fulfillment server 122 may transmit the requested content directly to device 102 across network 130 using one or more of the communications protocols outlined above. Further, fulfillment server 122 may allow the user of device 102 to log onto fulfillment server 122 to establish a secure communications channel through which the user of device 102 may access the requested content.

As discussed above, fulfillment server 122 may be associated with a queuing module, e.g., queuing module 312 of FIG. 3, that brokers and completes requests for content from devices in system 100. In an embodiment, fulfillment server 122 may transmit the requested content to queuing module 312 in block 808, and not directly to device 102. In such an embodiment, in block 808, fulfillment server may further transmit a message to device 102 that instructs device 102 establish a communication session with queuing module 312 to access the requested content. For example, an application program of device 102 may allow the user of device 102 to securely log onto queuing module 312 and access the requested content without directly communicating with fulfillment server 122, in contrast with the embodiments discussed above.

Further, the user of device 102, device 102, the service, or the requested content may be associated with a protocol that limits the ability of fulfillment server 122 to provide the service to device 102, or to deliver the requested content to device 102. For example, device 102 may be associated with a user in a location that prohibits the delivery by fulfillment server 122 of a subset of available electronic content. Further, device 102 may be associated with particular security protocols or communications-based protocols that, for example, block the transmission of content associated with an elevated security risk, or that that block the transmission of high-bandwidth content when device 102 has a experiences a poor wireless connection with network 130.

In such an embodiment, fulfillment server may, in block 808, identify a protocol associated with the user of the device 102, with device 102, or with the requested electronic content. Fulfillment server 122 may then filter the service or the requested electronic content based on the identified protocol, when it is determined that device 102 supports the service or requested electronic content, e.g., in block 806. For example, if the identified protocol were to block the transmission of electronic content having an elevated security risk, fulfillment server 122 may remove a portion of the requested electronic content associated with the elevated security risk, and proceed to deliver the filtered electronic content to device 102 in block 808.

Further, in an additional embodiment, fulfillment server may block the transmission of the requested electronic content when any portion of that electronic content is associated with an elevated security risk. In such an embodiment, fulfillment server 122 may transmit an error message to device 102 in block 808, instead of the potentially offending electronic content.

However, routine 800 is not limited to providing a service to device 102 upon receipt of a request for the service, e.g., a request for electronic content. In an embodiment, fulfillment server 122 may receive a request from device 102 for a particular service, and in response to the request, may identify additional services, e.g., related services, associated with the requested service. For example, fulfillment server 102 may identify that device 102 is receive notifications of available electronic content using a particular communications protocol, and further, fulfillment server 122 may identify that device 102 is configured to receive delivery of electronic content using a particular communications protocol or security protocol. In such an embodiment, fulfillment server 122 may initiate routine 800 to automatically provide such related services to device 102, either contemporaneously with the request, or at any additional or alternate time after receipt of the request.

Further, in additional embodiments, fulfillment server 122 may automatically provide a service to device 102 without any corresponding request for the service. For example, fulfillment server 122 may identify an available update to an operating system or application program executing on device 102. In such an embodiment, fulfillment server 102 may determine in step 806 that device 102 supports the identified operating system, and may automatically transmit the update to device 102 in step 808 using an appropriate communications and security protocol. The transmitted update may, in an embodiment, include executable files corresponding to the entire operating system or application program, or alternatively, may include executable files corresponding to updated modules of the operating system or application program.

Further, for example, fulfillment server 122 may automatically provide updated or current versions of authentication information to device 102 without specific requests. In an embodiment, fulfillment server 122 may obtain an updated version of a digital certificate, e.g., a SSL certificate, or an updated version of a cryptographic key, e.g., a key used in IKE exchange. Fulfillment server 122 may determine in step 806 that device 102 supports this updated authentication information, and in step 808, fulfillment server 122 may provide the updated authentication information to device 102 absent a specific request. In such embodiments, the updated authentication information may be transmitted to device 102 using an appropriate communications and security protocol.

Fulfillment server 122 may also leverage routine 800 to provide services related to device-specific actions. In an embodiment, fulfillment server may provide permissions for device 102 to perform a specific action, e.g., to post messages to a social networking or micro-blogging service such as Twitter. Moreover, fulfillment server 122 is not limited to providing the services describe above, with or without a specific request for the services. In additional embodiments, fulfillment server 122 may leverage routine 800 to provide device 102 with any of a number of additional or alternate services apparent to one of skill in the art and appropriate to a particular application.

FIG. 9 is a flow diagram of an exemplary routine 900 for determining whether a device supports a service, consistent with disclosed embodiments. As discussed above in reference to block 806 of FIG. 8, fulfillment server 122 may determine whether device 102 supports the service based an interaction with device capabilities server 126. Routine 900 provides further details describing how fulfillment server 122 interact with device capabilities server 126 to determine whether device 102 supports the service.

In block 902, fulfillment server 122 identifies a capability associated with the service. For example, and as discussed above, the capability can include, but is not limited to, an indication of allowable content, indications of communications and communications mechanisms, features of software supported by device 102, security protocols associated with device 102, location-specific capabilities and limitations (e.g., an ability to download and/or transmit files in certain geographical regions or countries), connection-specific capabilities and limitations (e.g., an ability to download electronic content when device 102 is roaming or has a poor signal), user-specific capabilities and limitations (e.g., user preferences), device-specific capabilities and limitations, or any additional or alternate capability apparent to one of skill in the art.

Once the capability is identified, fulfillment server 122 may transmit in block 904 the identified capability and at least a device type associated with device 102 (e.g., the device type identified in block 804 of FIG. 8) to device capabilities server 126. Further, additional information associated with device 102 (e.g., a version of an operating system, one or more software applications supported by the operating system, or information identifying one or more hardware components) may also be transmitted to the device capabilities server 126 in block 904. As discussed above in reference to block 804 of FIG. 8, the device type, and any additional information associated with device 102, may be obtained through interaction with a device management server, and additionally or alternatively, may be received directly from device 102, or may be stored locally at fulfillment server 122.

Upon receipt of the device type and the identified capability from fulfillment server 122, device capabilities server 126 may identify and retrieve a data record associated with the device type, and with any additional information associated with the device type. Device capabilities server 126 may then determines whether the retrieved record includes the identified capability, and may generate a response to fulfillment server 122 indicative of whether the retrieved record includes the identified capability, and as such, whether the device type is associated with the identified capability.

Fulfillment server 122 may receive the response from device capabilities server 126 in block 906, and based on the response, determines in block 908 whether device 102 supports the service. For example, if the response indicates that the device type is associated with the identified capability, then fulfillment server 122 may determine in block 908 that the service is supported by device 102. In such an embodiment, routine 900 passes back to block 808 of FIG. 8, which delivers the requested content to device 102. However, if it is determined in block 908 that the device type is not associated with the identified capability, then fulfillment server 122 determines that the service is not supported by device 102. Routine 900 then returns to block 810 of FIG. 8.

FIG. 10 is a flow diagram of an exemplary routine 1000 for associating a device type of a device with a capability of a service, consistent with disclosed embodiments. As discussed above, fulfillment server 122 queries device capabilities server 126 to determine whether device 102 supports the service. Routine 1000 provides functionality that enables device capabilities server 126 to determine whether device 102 supports the service.

In block 1002, device capabilities server 126 may receive a capability of a service and device information associated with device 102. For example, the received capability and device information may represent information transmitted from fulfillment server 122 to device capabilities server 126 in block 904 of routine 900, as discussed above in reference to FIG. 9.

As discussed above, exemplary capabilities include, but are not limited to, an indication of allowable content, indications of communications and communications mechanisms, features of software supported by device 102, security protocols associated with device 102, location-specific capabilities and limitations (e.g., an ability to download and/or transmit files in certain geographical regions or countries), licensing protocols, connection-specific capabilities and limitations (e.g., an ability to download electronic content when device 102 is roaming or has a poor signal), user-specific capabilities and limitations (e.g., user preferences), device-specific capabilities and limitations, or any additional or alternate capability apparent to one of skill in the art.

Further, and as discussed above, the device information includes at least a device type associated with device 102. For example, the device type may be determined by fulfillment server 122 through an interaction with a device management server, e.g., device management server of 124 of FIG. 1, and additionally or alternative, the device may provide the corresponding device type directly to fulfillment server 122 in, for example, the request for the electronic content. In additional embodiments, the device information may also include, but is not limited to, a version of an operating system of device 102, one or more application programs supported by the operating systems, a hardware component of device 102, and any additional or alternate information apparent to one of skill in the art.

In block 1004, device capabilities server 126 may retrieve a data record associated with the received device type, and additionally or alternatively, with the received device type in combination with any additional device information. For example, device capabilities server 126 may retrieve the data record from a plurality of records stored within a corresponding data store, e.g., capabilities data store 606 of FIG. 6. Further, in an embodiment, the device type and additional device information associated of the retrieved record matches corresponding information associated with device 102 and received from fulfillment server 122 in block 1002.

Device capabilities server 126 may compare the received capability with corresponding information within the received record in block 1006 to determine whether the retrieved record includes the attribute of the retrieved record. For example, the capability of the requested content may represent an allowable file type, e.g., a PDF file, and device capabilities server 126 may compare the attribute against corresponding device capability data within the retrieved record, e.g., capabilities information 712 of FIG. 7. Device capabilities server 126 may generate a response to the fulfillment server in block 1008 that includes the results of the comparison.

As discussed above, capabilities information 712 include a capability 714 and a corresponding value 716. In an embodiment, device capabilities server 126 may determine whether the received capability matches capability 714. If it were determined that the received capability matches capability 714, the device capabilities server 126 generates a response in block 1008 that includes at least the received data type, the received attribute, and value 716 corresponding to capability 714.

Once generated in block 1008, device capabilities server 126 may transmit the response in block 1010 to fulfillment server 122. In an embodiment, the response may be transmitted over network 130 using one or more of the communications protocols discussed above. Once the response is received, fulfillment server 122 may determine whether the device supports the service, e.g., in block 908 of routine 900, based on at least the received response.

For example, if the received capability is an allowable file type of requested content, e.g., “PDF,” device capabilities server 126 would match that received attribute to “PDF” capability 714, and determine that corresponding value 712 is “TRUE.” As discussed above, may include, for example, the device information, at least the received capability, e.g., PDF content, and the corresponding value of “True.” Further, for example, if the received capability does not match any device capability within the retrieved record, then a similar response would be generated by device capabilities server 126 in block 1008 to include, for example, the received data type, the received capability, and an indication that the retrieved attribute is not associated with the corresponding device-specific information. One of skill in the art will recognize that the response generated by device capabilities server 126 in block 1008 may include any subset of the information described above, or any additional information appropriate to the retrieved data record, the received attribute, and/or the received data type.

As one of ordinary skill in the art will appreciate, one or more of blocks 802-810, 902-908, and 1002-1010 may be optional and may be omitted from implementations in certain embodiments. Furthermore, functionality provided by one or more of blocks 802-810, 902-908, and 1002-1010 may be subdivided into multiple blocks.
